Referring to fig. 1, a first mounting surface 11, a second mounting surface 12, and a connecting surface 13 connecting the first mounting surface 11 and the second mounting surface 12; the first mounting surface 11 and the second mounting surface 12 are located on the same side of the connecting surface 13 and intersect with the connecting surface 13; the first mounting surface 11 is provided with a first preset number of first mounting holes 111, and the second mounting surface 12 is provided with a second preset number of second mounting holes 121.

In one embodiment, the second mounting surface 12 is perpendicular to the connecting surface 13.
In an embodiment, the first mounting surface 11 and the second mounting surface 12 are located on the same side of the connecting surface 13, and the first mounting surface 11 and the second mounting surface 12 are oppositely arranged.
In an embodiment, the first predetermined number of the first mounting holes 111 on the first mounting surface 11 is at least two.
In an embodiment, the second predetermined number of second mounting holes 121 on the second mounting surface 12 is at least two.
in one embodiment, the first mounting surface 11 is provided with a first rib structure 112; the second mounting surface 12 is provided with a second reinforcing rib structure 122; the attachment face 13 is provided with a third bead structure 131.
In one embodiment, the first rib structure 112, the second rib structure 122 and the third rib structure 131 together comprise a reinforcing rib. In the structural design process, the overhanging surface of the structural body is possibly too large or the span is too large, in such a case, the load which can be borne by the connecting surface 13 of the structural body is limited, and a reinforcing plate, commonly called a reinforcing rib, is added on the common vertical surface of the two combined bodies to increase the strength of the connecting surface. The rigidity of the auxiliary support 1 is improved by providing a reinforcing rib structure. Specifically, the reinforcing ribs are distributed on the first mounting surface 11, the second mounting surface 12 and the connecting surface 13 at positions with relatively low strength, so that the thickness of a support metal plate can be reduced while the strength and modal requirements are ensured, the waste of materials is reduced, and the cost is saved. Specifically, the reinforcing rib structures are distributed at the middle positions on the first mounting surface 11, the second mounting surface 12 and the connecting surface 13. Specifically, the reinforcing rib and the auxiliary support 1 body are integrally formed, and the process is simple and reliable.
In one embodiment, the first rib structure 112, the second rib structure 122 and the third rib structure 131 are hollow reinforcing ribs.
In one embodiment, the auxiliary support 1 is integrally formed. The auxiliary support 1 is simple in structure, mature in process, free of changing the assembly relation of the existing vehicle and good in implementation feasibility. Specifically, the weight of the auxiliary bracket 1 is 0.25Kg, so that at least 4Kg is required to be increased compared with the weight of the suspension bracket 3, the increased weight is small, resources are saved, the cost is reduced, and the light weight design concept is met.
In one embodiment, the first mounting surface 11 is used to be fixed to the motor 2 through the first mounting hole 111 and a first fixing bolt. Specifically, the first mounting surface 11 is fixed to a housing end surface boss of the motor 2 through the first mounting hole 111 and a first fixing bolt. The second mounting surface 12 is used for being fixed to the suspension bracket 3 through the second mounting hole 121 and a second fixing bolt. Specifically, the second mounting surface 12 is used for being fixed to two bosses on the lower side of the suspension bracket 3 through the second mounting holes 121 and second fixing bolts, so that the suspension bracket 3 has at least two more fixing points, and the mode of the suspension bracket 3 is improved. Specifically, motor 2 is electric automobile's motor 2 engine promptly, suspension support 3 is electric automobile's suspension support 3, and the support mode of electric motor car than traditional car will be on the high side, all has certain requirement to its mode when suspension support 3 generally designs, because whole plantago cabin layout problem, sometimes suspension support 3's structural design often can not reach the mode requirement, current suspension support 3 generally all can adopt the material of higher strength, improve suspension support 3 mode through improving rigidity, or through increasing amplitude peak value when gimmick resonance such as quality reduction. However, the weight of the entire bracket is increased by any method, and the design requirement for light weight cannot be met. Therefore, the first mounting surface 11 of the sub-bracket 1 is fixed to the motor 2 through the first mounting hole 111 and the first fixing bolt, and the second mounting surface 12 of the sub-bracket 1 is fixed to the suspension bracket 3 through the second mounting hole 121 and the second fixing bolt. Therefore, the effect of improving the overall mode of the suspension bracket 3 is achieved under the condition that the weight of the suspension bracket 3 is not greatly increased and the rigidity of the suspension bracket 3 is not improved. The mode is the natural vibration characteristic of the structural system. The free vibration of the linear system is decoupled into N orthogonal single degree of freedom vibration systems, corresponding to the N modes of the system. Each mode has a specific natural frequency, damping ratio and mode shape. These modal parameters may be derived by calculation or experimental analysis, such a process of calculation or experimental analysis being referred to as modal analysis. The vibration characteristics of each order mode of the mechanical structure in a certain susceptible frequency range and the vibration response results of the mechanical structure under the excitation action of various vibration sources in the frequency range and inside or outside can be obtained through a structural mode analysis method, and the modal parameters are obtained through the structural mode analysis method and combined with related tests, and the modal parameters are used for redesigning the structure by means of the special parameters. A mode is a characterization of the vibration system characteristics that constitute the most fundamental vibration mode of complex vibration of various body structures. In order to avoid resonance and reduce noise in automobile use, the natural frequency of the structure vibration and its corresponding mode shape need to be known. The final objective of the modal analysis is to obtain modal parameters, and provide a basis for the dynamic characteristic analysis, fault diagnosis and prediction of the structural system and the optimal design of the dynamic characteristic of the structure. The excitation of an automobile in the driving process is generally divided into road excitation, wheel imbalance excitation, engine excitation and transmission shaft excitation. The road surface excitation is generally determined by road conditions, at present, on the better road surfaces of expressways and common cities, the excitation frequency is more 1-3Hz, and the influence on low-frequency vibration is generally large; the excitation frequency caused by the unbalance of the wheel is generally lower than 11Hz, and along with the improvement of the manufacturing quality and the detection level of the conventional rim, the excitation component is smaller, so that the excitation frequency caused by an engine is easily prevented from being generally higher than 23Hz, and the excitation component is larger; the general speed of a vehicle in a city is controlled to be 50-80 Km/h, the general speed of the vehicle on an expressway is controlled to be 80-120 Km/h, the frequency range of vibration caused by unbalance of a transmission shaft is above 40Hz, and the excitation component is small. The external excitation sources can cause the vehicle door to generate resonance, bring noise, greatly reduce the riding comfort of the vehicle, cause the shaking and cracking of a pulling piece, the fatigue damage of parts, the damage of a surface protective layer of the vehicle door, weaken the corrosion resistance of the vehicle door and the like. These external excitation sources may also cause resonance of the motor 2, causing the motor 2 to shake and crack, and fatigue damage to parts.
In an embodiment, the auxiliary bracket 1 is made of a sheet metal material. The sheet metal is a comprehensive cold working process for sheet metal (generally below 6 mm), including shearing, punching/cutting/compounding, folding, welding, riveting, splicing, forming (such as automobile bodies) and the like. The remarkable characteristic is that the thickness of the same part is consistent.
Referring to fig. 2, the present invention provides a motor damping mechanism, including: the auxiliary bracket 1 and the suspension bracket 3 of any of the above-described suspension brackets 3; the first mounting surface 11 of the auxiliary bracket 1 is fixed with the motor 2 through the first mounting hole 111 and a first fixing bolt; the suspension bracket 3 and the second mounting surface 12 of the auxiliary bracket 1 are fixed by the second mounting hole 121 and a second fixing bolt. Under the condition of not influencing the existing structure, materials and weight of the suspension bracket 3, the overall mode of the suspension bracket 3 is improved, and the problems of resonance and abnormal sound caused by the coupling of the mode of the suspension bracket 3 and the modes of other vehicle parts are avoided. Specifically, the first mounting surface 11 is fixed to a housing end surface boss of the motor 2 through the first mounting hole 111 and a first fixing bolt. The second mounting surface 12 is used for being fixed to the two bosses on the lower side of the suspension bracket 3 through the second mounting holes 121 and the second fixing bolts, so that the suspension bracket 3 has at least two more fixing points, and the mode shape of the suspension bracket 3 is improved. The effect of improving the overall mode of the suspension support 3 can be achieved on the basis of not greatly increasing the weight of the suspension support 3. Specifically, the final mode is improved by 312Hz compared with the original mode without the auxiliary bracket 1, and the design requirement of the suspension bracket 3 is met.
The operation of the auxiliary bracket of the suspension bracket will be described in detail as follows: the first mounting surface of the auxiliary bracket is fixed with the motor through the first mounting hole and the first fixing bolt; and the suspension bracket and a second mounting surface of the auxiliary bracket are fixed through the second mounting hole and a second fixing bolt.

Effectively overcomes various defects in the prior art and has high industrial utilization value.
